To generate LINE stickers from text concepts, you describe your idea and the workflow uses the Gemini API to produce artwork. The script then automatically resizes the image, removes the background, and validates the size constraints to ensure the output is fully LINE-compliant.

Yes, you can create animated APNG stickers for LINE with Python and Pillow. The workflow handles frame sequencing, alignment, and size constraints automatically, assembling the generated frames into a compliant APNG animation ready for upload.

Automating sticker image generation requires Python 3.10 or higher, a valid GEMINI_API_KEY, and the project scripts. You also need to set up a resource layout containing scripts, references, and assets folders as detailed in the project documentation.

Sticker size validation fails when images do not meet LINE's specific dimension limits. The workflow uses Pillow to automatically resize and format the Gemini-generated artwork, applying background removal and strict size validations to ensure your static stickers pass LINE's compliance checks.

Static sticker creation from multiple concepts can be batch processed by running the project scripts with different text inputs. The Gemini API generates each individual image, while the Python scripts handle the repetitive post-processing and LINE formatting tasks automatically.
